"SPP" allows normal speed operation, but in one direction only. "EPP" allows
bidirectional parallel port operation at maximum speed. "ECP" allows the parallel
port to operate in bi-directional mode and at a speed faster than the maximum
data transfer rate. "ECP + EPP" allows normal speed operation in a two-way
mode

EPP Mode Select [EPP1.7]
This field allows you to select EPP port type 1.7 or 1.9.

ECP Mode Use DMA [3]
This selection is available only if you select "ECP" or "ECP + EPP" in the Parallel
